Subject [jira] [Commented] (HUDI-686) Implement BloomIndexV2 that does not depend on memory caching
Date Thu, 19 Mar 2020 17:19:00 GMT

    [ https://issues.apache.org/jira/browse/HUDI-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17062781#comment-17062781
] 

Vinoth Chandar commented on HUDI-686:
-------------------------------------

Running a local microbenchmark, I actually found that the extra shuffling in V2 Implementation
(shuffles input two times, vs just 1 time caching and shuffling just the keys in the current
impl) actually makes it a tad slower.

> Main goals here is to provide a much simpler index, without advanced optimizations like
auto tuned parallelism/skew handling but a better out-of-experience for small workloads.
